We don't generally "etch" integrated circuits, but, rather, we "grow" them layer by layer on a silicon substrate.
A printed circuit board. abbrev- PCB. A PCB is thin copper attached to a non-conductive material. No, a printed circuit board is not a semiconducting material. Integrated circuits are created on a substrate, usually silicon or sapphire.
A long time ago, after ways to make semiconductors were discovered - around 1955 - circuits were made by using a separate transistor to perform each function. That took a lot of real estate on a circuit board and meant severely decreased functionality when handling high frequencies. Nowadays all of those transistors and their associated circuit components can be laid out and etched into an area that is less than the size of the point of a pin, which is why they are called INTEGRATED CIRCUITS. The material that is used is a wafer of specially-prepared semiconductor material that has been doped differently in various nano-layers to allow the various circuit elements to be formed by selective etching.
A microchip is not a microcosm or microfilm. A microchip is a small piece of semiconductor material on which integrated circuits are etched with electronic circuits for functions like processing and memory.
Basically they can be considered the same thing. Micro chip may refer to the fact that it contains a micro processor. A microprocessor is an integrated circuit that is designed to handle instructions from a software program and form the core of a computer system. Integrated circuits are any type of device, that has many components etched onto a single piece of silicon and embedded in a plastic package with conducting legs. They include microprocessors, but could be amplifiers, logic gates, memory storage, complete radios, or other dedicated circuits that do one job very well.
The circuits are simply called microchips,because these circuits are too small to be seen clearly with a naked eye.
Memory cells are typically etched on silicon-based materials, such as silicon wafers, due to the material's properties that make it suitable for storing digital information in electronic devices.
According to a Google search "etched into our memories" has 539,000 hits."Etched in our memories" has 458,000 hits."Etched onto our memories" has only 3,070 hits.Accordingly I recommend "Etched into" or "Etched in"Dictionary.com also includes the sample sentence: "Adeep canyon was etched intothe land by the river'srushing waters."
The fancy mansion's windows were even fancier with a picture of a crown etched in them.
Integrated circuits are etched onto a silicon chip. All the elements of a complete circuit can be included on a small slice of silicon, including transistors, resistors, capacitors and diodes. It takes several stages of a photographic and chemical process, to build up the design in a clean room to create a chip. After the initial design, they can be mass produced at minimum material cost. The chip is encapsulated in a small plastic box and legs sticking out, enabling it to be soldered onto a board with other chips and discrete components. They are important to computers, as the miniturisation and complexity allows computers to be buit into a small enclosure at a reasonable price.
Etched in Blue was created in 1987-05.
The word etched is a verb. It is the past tense of etch.
